-SPECIFICATION forming part of Letters Patent No. 322,112, dated July14.1885.

Application filed May 6, 1884.

To all whom it may concern.:

Be it known that I, Goni-REY H. LASAR, of St. Louis, Missouri, have madea new and useful Improvement in Barb-Wire Machines, of which thefollowing is a full, clear, and exact description, reference being hadto the annexed drawings, making part of this speciication, in which-Figure 1 is a plan of the improved machine; Fig. 2, aside elevation,partly in section, thereof; Fig. 3, a cross-section, upon an enlargedscale, on the line 3 4 of Fig. 2, the parts being as when the barb hasbeen formed; Fig. 4, a similar section, the parts of the barb-formingdevice being in a different position; Fig. 5, a

The same letters of reference denote the same parts.

The present construction is an improvement in that class of barb-wiremachines which make a four-point barb.

In its construction and operation the machine under consideration issubstantially as follows: Three of the reels are held in the iiier atwhat may be termed the rear end of the machine.7 The fourth reel for theremaining one of the four wires is not shown. It may be located at anypoint from whence its (No model.)

wire can be led to the flier. The iiier is fastened to a stock whichrotates in a suitable bearing. Within the stock is a barrel, and thebarrel in turn containsa core. The strandwires are fed through the core.The two barb-wires are fed along upon opposite sides of the stock, andthence through the head upon the forward end of the barrel, and thenceacross the face of the head and so as to pass between the strand-wires.A pair of arms pivoted to the same bearing are adapted to close towardeach other as the barb-wires pass between the strand-wires, and by meansof formers, which are attached, respectively, to the arms, are made,rst, to hold the projecting ends of the barb-wires so that they shall beproperly intertwined upon the strand-wires,

and, second, by means of shears carried, respectively, by the arms tosever the barbwires. l

The improvement relates partly to various details of construction andpartly to the general combination of the various parts of the machine,whereby a simple, effective, and rapidly-working construction isobtained.

A, Figs. 1, 2, represents the improved ma-- It is wattached to throughwhich slot one of the wires, if .de-

sired, can be passed. The `other wires lead from the reels respectivelyand aroundthe sheaves b2 b2, substantially as indicated by the arrowsand the broken lines in Fig. 8, and from the forward sheaves the wirespass down the tubes b3 b* to the stock C-that is, the strand-wires passthrough the tubes b3 to and around the sheaves b5 b5, Figs. 10, 12, andthe barb-wires pass down the tubes b* b4, Fig. 9, to and around thesheaves bi be. When one of the strand-wires, instead of being led aroundthe sheaves b2, is passed through the slot b of IOO the bar b, it iscarried from theslot past one of the sheaves b5. From the sheaves b5 b5the strand-wires pass into and through the grooves ff, respectively,which are extended longitudinally throughout the length of the core F.The barb-wires are led from the sheaves b6 b through the passages c c,respectively, of the stock G. From the passages c c the barb-wires areextended upon opposite sides of the stock, past the dogs G G and throughthe tubes H H, which are attached to the stock, and substantially asshown in Fig. 14. From the tubes H H the barb-wires pass, respectively,into thetubes I I. These lastnamed tubes are held and extended throughthe head J, and after passing through the head are made to converge infront of the forward end of the core F. The head .I is mounted upon thebarrel K. The barrel contains the core F, and the head, barrel, and coretogether have a reciprocating movement, the barrel extending rearwardlyinto the stock, and being adapted to be moved longitudinally therein.The stock is provided with a gear, L, which engages with a gear, M, uponthe driving-shaft N. This driving-shaft is provided at its forward endwith the bevel-gear N', which engages with the bevel-gear O upon thecrank-shaft O. A pitman, P, leads from the crank-shaft O rearwardly, andis jointed at I to a bracket, Q, which in turn is fastened to the slideR. The slide is provided with a standard, R, in which is journaled thehead J. The motion of the shaft N, therefore, through the parts N O O PQ R R causes the head J, barrel, and core to be moved forward andbackward in the stock of the machine. The head J, the barrel K, and coreF are adapted, however, to rotate with the stock in the customarymanner, and to that end the head may by any suitable means (not shown)be securedto the barrel, and the barrel may be furnished with thesplines 7c 7c, Figs. 13 and 16, which work in corresponding grooves inthe stock, and the core and barrel are also suitably connected so as tomove together.

S S representa pair of arms pivoted to the bearing S'l on the slide R.The upper ends of the arms are caused to move toward each other by meansof the cams S3 S4, which, by means of the sleeve, (shown but notlettered,) are attached to the shaft N, and the spring S5 operates towithdraw the upper ends of the arms from each other, the two positionsbeing shown, respectively, in Figs. 3, 4. The arms S S are respectivelyprovided with the barbformers T T. That part, t, of the former againstwhich the projecting end w of the barb W presses is notched, as shown att', Figs. 5, 6, 7. As this part t is subjected necessarily to a greatdeal of wear, and in consequence is liable to be worn away, it is maderemovable from the main portion of the former, and to this end the partt is provided with the shank t2, Fig. 7, which is adapted to be insertedin a mortise of corresponding shape inthe main part t3 of the former,and

therein secured by means of a set screw, t4. The former is also providedwith the shear t5.

The operation of the barb-formers is indicated by the various positionsof the parts shown in Figs. 17 18, 19. Vhen the ends w w are suitablyprojected from the tubes I I, as in Fig. 17, the barb-formers areoperated to close toward each other, bringing the formers and the wiresw w into the position shown in Fig. 18. By continuing to close thebarb-formers the wires w w are suitably intertwined upon thestrand-wires VV" W', as shown in Fig. 19, and the shears t5 t5 thenoperate to sever the wires w w from the main portion of the barbwires,and the barb W is nally completed, as shown in Fig. 21. .The nishedbarb-wire passes over the sprocket-wheel X, and thence to the customarywheel. (Not shown.) Vhen the part t of the barbformer is worn out, a newone is inserted in its place inthe former. One, S', of the arms S S ismade shorter, as shown, than the other arm, in order to swing thebarb-former Tl past the barb-former T in forming the barb. In thusswinging the barbformers in arcs they can be made to act to better'advantage in forming the barbs than if the barb-formers are moved pasteach otherin parallel lines. It also enables the machine to be madelighter and its construction to be simplified. The dogs G Gare adjustedby means of the stops G G2. The center reel, E, is supported directlyupon the bar b. The other reels, EFP, are j ournaled upon the sleeves ce2, respectively, which are, and as shown at e361, Figs. 8, 12,respectively screwed into the iiier and stock, and respectively at therear and forward ends of the flier. The bar b passes through thesleeves. This enables the reels E E2 to be supported in the iier whenthe reel E is withdrawn therefrom.

As shown in Fig. 8, two of the reels are for the barb-wires, and one ofthe strand-wires is led from the reel mentioned as not being attached tothe flier, and such strand-wire may be led through the bar b or aroundthe iiier, and, in such last case, it may be led in either of thedirections indicated by the arrows bf bw, respectively. The bar b, atits outer end, is provided with a lug, bw, which, when thc bar is inplace, enters a corresponding notch, b3", in the dier. The lu g, thenotch, and one of .the grooves f are relatively arranged so as to causethe groove bto coincide with the groove f when the bar b is in place.The bar b may also have a handle, 615. Having but a single groove, b, inthe bar b insures the proper relative adjustment of the groove to thatone of the grooves f f with which the groove b should coincide.

I claim- A j 1. The combination of the arms S S, pivoted to the centerS2, and provided, respectively, with the formers 'I T', with the cams S3S4, the spring S5, the shaft N, the head J, the barrel K, the core F,and the slide It, as described.

2. A barb-wire machine having the barb- ILO formers T T attached to apair of arms, S S, constructed as described, and pivoted to the samecenter, S2, and J[hereby adapted to swing the barb-formers in arcs andpast each other in forming the barb, as described.

3. The barb-former T, having the detachable part t, as and for thepurpose described.

4. The combination of the stock C, the frame D, the gears L M N O, thecore F, the barrel K, the head J, the shafts N O', the pitman P, thebracket Q, the sleeve carrying the cams S3 S4, the slide R, the standardR', and the arms S S', pivoted to the bearing S2 and carrying theformers T T, as described.
